Scientists use both joules and calories. They are two different things. That cake that you just ate is a whole lot of calories. It is making you fat as a pig. You had better do something about it. You look in the mirror and decide it is now or never. You put on your jogging shoes and start moving. You look at your watch and take off. As you move and use calories and time, you are using joules.

Why do scientist use the joule as the unit of measurement of energy instead of calorie?
Because it is defined by fundamental SI units, ie the meter and the Newton, which is a force. 1 Joule is the energy used to move 1meter against a force of 1 Newton.
Nutritionists use what to measure how much energy you get from foods?
Traditionally, this was measured in calories, or Calories (equal to 1000 calories - note the uppercase!). But the tendency is to use the official unit of energy - the Joule. This is the same unit that is used to measure any type of energy.
What are the units for energy?
In the SI system the units are Joules. You can also use ftlbf (footpoundforce). For thermal energy use calories or BTU
How do you use joule in a sentence?
You just did use the word joule in a sentence.
How can i use the chemistry word joule in a sentence?
The reaction consumes more joules than supplied by the technobabble. The large Hadron Collider produces collisions in the order of 1 microjoule per particle. Outside of America energy food energy is often expressed in joules instead of calories.
Why is it best for scientist to use the scientist name of an organism instead of a common name?
Scientific names never differ among scientists.
What heat measurements does the US use and the world?
The SI unit for energy (including heat energy) is the joule. It is still quite common, in many cases, to use the old unit calorie instead.
Why scientist use SI units instead of units such as inches and gallons?
The idea is to use an international standard - the same units everywhere.
Why would a scientist use a coloured liquid instead of water in a thermoscope?
If the liquid is blue, then it is most likely iodine. They would use iodine instead of water because it is easier to see and if i am not mistaken, it makes things clearer.
Where are calories stored in the body?
If you eat too many calories, instead of using them for energy your body stores the energy as fat to use at a later time. It is stored in your liver, muscles and fat cells.
Why do you use kilojoules to measure?
Some times the amount of energy will be in larger amount. If we use joule then larger number with many zeros has to be used. So we use kilo joule then smaller number would fulfill our need.
How do I calculate euro calories to American?
The calorie is based on metric mesurements and is therefore the same anywhere in the world. However use of calories is discouraged and instead kJ should be used. kJ are easier to calculate.
